My husband and I are thinking of buying the Canon Optura Xi camcorder soon (in our opinion, the best DV camera at this range). Because I run so many OSes I always have 'embedded' in me this "thing" to only buy supported hardware by the major OSes. I am sure Optura's DV part will work fine with some Linux tools, but then what? How do I easily edit my... masterpiece and burn DVDs or VCDs via an integrated solution and send them to our families in Greece and France?

mjpegtools isn't command-line only. It comes with a front-end (sort-of) called glav. A fancier frontend is Linux Video Studio. If you're looking for a command-line video editor, try mplayer.

"AVIdeMux - A kind of weird-looking app" just doesn't cut it as a description of a program's strengths and shortcomings, especially in a piece that claims to be about the "state" of a field. Have you actually tried it? Or did you just rate based on the screen shots?
